To all whom it may concern:

Be it known that I, DAVID R. SAUNDERs, a citizen of the United States,residing at Co lumbus, in the county of Lowndes and State ofMississippi, have invented certain new and vuseful Improvements in CarBumpers, or

which the following is a specification.

The object of the present invention is the provision o'novel means forretarding the .movement of rolling stock and preventing the same frompassing over the extremity of the track, and the invention contemplatesan improved construction whereby this result is accomplished without anysudden shocks or jars which might have a vtendency to injure the rollingstock or the contents thereof.

vTo this end the invention resides broadly 4in the provision of a trackin which the end portion thereof has an undulating formation so as toprovide a series of ridges and intervenin depressions over which the.wheels of the ro ling stock must pass and which serve to utilize theenergy of the moving car in. imparting an up and down movement thereto.

For a full understanding of the invention and the 4merits thereof andalso to acquire a knowledge of the details of construction and themeansfor eli'ecting the result, reference is to be had to the followingdescription and accompanying drawings, in which:

Figure l is a side elevation of a ear retard- ,ing'l track terminationembodying the invention, the desired slope being imparted to the saidtrack termination by grading the road bed. Fig. .2 is a top plan view oithe same. Eig. 3 is a side elevation showing a slight modification inwhich 'the necessary slope is obtained by blocking up the track insteadof by grading the road bed as shown in Fig. l. wCorresponding and likeparts are referred tain the following description and indicated end ofthe track abut against the respective.

in all the views oi the drawings by the same reference characters.

v Referring to the drawings which show one `embodiment of the invention,the numerals 1 indicate the rails of the main portion of the track whichis level or as near level espossible, the said rails being of the usualT section and. being supported upon a road bed of any suitableconstruction. The rails 2 at the rails i and are disposed in alinementtherewith and are bent so as to impart an undu1atcharacter to the endportion of the track.

' These rails 2 preferably have a attened formation and engage thellanges of the car wheels, the tread portions of thewheels being heldspaced from the rails. 'ibis construction is found advisable since inmany cars the brake shoes extend downwardly to within a very shortdistance of the track rails and would otherwise come into contact withthe curved portions of the rails 2 and be injured. Guard rails 3 whichare bent in a manner corresponding to the rails 2 are secured theretoand engage the flanges of the wheels to guide .the said wheels in theirmovement and prevent derailment of the car. Attention is furtherdirected to the fact that the undulations ol' the rails 2 are graduallyincreased in magnitude from the level or main portion of the track tothe extremity thereof so that each succeeding ridge over which the carwheels pass is higher than the next preceding ridge and each depressionis in a similar manner slightly deeper than the next precedingdepression. In this manner the rolling stock is gradually brought to astandstill Without the production' of any sudden shocks or jars whichwould have a tendency to injure the same or the contents thereof.. Thismanner of retarding the speed of the rolling stock has a furtheradvantage in that when a train is being backed and the end car reachesthe rails 2 the up and down movement of the car imparted thereto by theundulating character of the said rails will send a series of impulsesthrough the train and will warn the engineer in ample time to reversethe engine or bring the trainv to a stop.

In addition to bending the rails 2 so as to` provide the ridges andintervening depressions, the end. portion of the track is preferablylaid upon a grade of about ten er cent., this grade serving the double'function of aiding in checking the movement of the rolling stock andalso of enabling the rolling stock to be readily pulled away from theundulating portion of the track. The eX- tremities of' the rails 2 areextended u wardly at -4 sc 'that should the car not e stop ed before itreaches the end of the trac the wheels will be engaged by the saidupturned ends 4 which will act in a manner similar to lthat of theordinary bumper ost. Any suitable means may be provide for su portingthe rails 2 and the road bed may eit er be inclined upwardly to impartthe desired grade .to this portion oi the track, or the rails 2 may beblocked up as found most 2 scanjet.

desirable. With this construction it :will be obvious that before a carreaches the extreme end or termination of the track it will be. causedto pass over the undulating rails 2 and the energy of the car will beutilized in impartingV an up vand down vibratory movement thereto. Inthis Amanner the car is'gradually brou ht to a stop without the injurywhich Wou d bei-.ncident to the sudden jar produced by a bumper postsuch asA is vcommonly employed. Attention may again be directed tothe'fact that the car Wheels after reaching the rails 2 roll upon theirflanges, thereby preventing the brake mechanism vfrom coming intocontactwith the rails 2 and causin injury.
